The Indiana Soldiers and Sailors Monument is a 284 ft 6 in (86.72 m)-tall neoclassical monument located on Monument Circle in the center of Indianapolis. It was designed by German architect Bruno Schmitz and completed in 1901.

The Monument was erected to honor Hoosiers who were veterans of the American Revolution, territorial conflicts that partially led up to the War of 1812, the Mexican-American War, the US Civil War, and the Spanish American War. In addition to its external commemorative statuary and fountains (made primarily of oolitic limestone and bronze), the basement of the monument contains the Colonel Eli Lilly Civil War Museum, a museum of Indiana history during the American Civil War.

At the top of the Monument is an observation deck that can be reached by stairs at no cost or by elevator for a $2.00 charge (elevator brings you to the level just under the observation deck, with 30 additional steps). The staircase contains 331 steps, 330 of which are numbered. In 1902 the cost to build this Monument was (US) $598,318. It has been estimated that building a similar structure today would cost over $500,000,000.
